Abstract

L'invention concerne un écrou autobloquant comprenant un corps d'écrou principal et un corps d'écrou déformable. Le corps d'écrou principal présente un renfoncement débouchant dans un trou intérieur fileté dans lequel un filetage interne fait x tours. Le corps d'écrou déformable possède un rebord externe et un trou intérieur fileté dans lequel un filetage interne fait y tours. Le rebord externe du corps d'écrou déformable est fixé au corps d'écrou principal de façon telle qu'un espace de détente est formé entre le corps d'écrou déformable et le renfoncement. Le rapport x:y est d'environ 2:1.
